Keep in mind that that difference likely had much more to do with a running back whose initials are AP then Jackson. Also, that doesn't change the statistical analysis above. As prieviously stated, I'm a Bears fan - the two Minny W's vs. the beloved had absolutely nothing to do with Jackson.
But Peterson played in all four of the games that Jackson did not start...
Let's take a look at the 4 games he didn't start:
KC- they were just outplayed. AP had 100+ yards and played well. The QB Holcombe didn't play that bad, just didn't get a TD.
GB- Holcombe played very well this game, but GB is really the only team that could hold AP to a "decent" game... he ran for 112 and (yes I know this isn't much of a point) but
take away his 55 yard run (not for a TD) and he only had 67 yards on the ground... and as GB fan, AP did not look good that game.
PHI- They didn't have a chance at winning this game. AP ran for 70 yards
GB again- GB is good and they knocked AP out of the game. Bollinger wasn't that bad.
So really, those 4 losses have more to do with AP not being as ridiculously effective as he can be. Bollinger and Huard combined those 4 games to give what Jackson typically gives. So the fact that they lost those games without Jackson has nothing to do with Jackson. Has more to do with AP
I'd trust that Bears fan up there, he knows what it looks like when a QB needs to be given the ol' heave-ho, yet everyone is dilusional thinking he can be good (See Rex Grossman)
